Place the characteristics of a compound action potential in the correct order. (greater/less) than the concentration of K+ in the ICF.1 greater/less) than the concentration of Na* in the ICF -a. depolarization b. hyperpolarization c, repolarization

Explanation / Answer

13 In a typical excitable cell ,the concentration of K+ in the ECF is less than the concentration of K+ in the ICF.

14. In typical excitable cell, the concentration of Na+ in the ECF is greater than the concentration of Na+ in the ICF.

15. Correct order

a. depolarization c. repolarization and then b.hyperpolarization

Remember as a rule of thumb that concentration of Na+ is greater in ECF than ICF and the concentration of K+ is greater in ICF than ECF.
